In practice though I think it’s just a painful experience since everything that’s easy to do on your computer now needs a brand new, bespoke and paid solution.
Gitpod is just a free VSCode instance. On a computer you have the option to use this cloud instance; on the iPad you must use it.
it's mostly a novelty to ':0' at but i'm sure it's useful for showing people how to get started. i could easily see an intro workshop making use of gitpod and advertising it as a platform agnostic beginner course!
of course with some exceptions like hardcore gaming
Laptops are better at some other things, but if you do very much of the above you're probably gonna have a tablet, too. If you don't do much of what laptops can do that iPads can't (mostly for software-limitations reasons), then replacing the laptop with your tablet might be a viable approach. You can't really do the reverse without a bunch of extra hardware (admittedly, you do need a keyboard and some kind of pointing device for the iPad-as-laptop-replacement thing, too) or just carrying two devices.
